WA-TX-03-R and
WA-RX-03-R |

Regulatory compliance of the WA-TX-03-R and the WA-RX-03-R
The WA-TX-03-R and the WA-RX-03-R are designed for embedding in other
equipment.
(Products incorporating the WA-TX-03-R and the WA-RX-03-R are
henceforward referred to as final products.)
The European regulation applicable to the WA-TX-03-R and the
WA-RX-03-R is the R&TTE Directive 1999/5/EC.
The WA-TX-03-R and the WA-RX-03-R are intended to be used for the
Radio Microphones defined in the ERC/REC 70-03 Annex 10 and for the
Wireless Audio Applications in the ERC/REC 70-03 Annex 13 (EN 301
357*)
The conformity assessment for the WA-TX-03-R and the WA-RX-03-R were
completed in accordance with the R&TTE Directive Annex II (RX) & III
(TX) procedures, and the Declaration of Conformity is attached to this
manual.
* NOTE: EN 301 357 defines the equipment covered by
its standard and the output power limits depend on the equipment type.
The WA-TX-03-R meets the output power limits allowed for all equipment
types except for “in-vehicle cordless” and “personal cordless”. If the
WA-TX-03-R is used for “in-vehicle cordless” or “personal cordless”
equipment, the manufacturer is required to design the final product
within the specified output power limit and to perform the conformity
assessment of the final product to EN 301 357.
Cautions related to regulatory compliance when embedding WA-TX-03-R/WA-RX-03-R
1. Antenna for the WA-TX-03-R
The WA-TX-03-R is supplied without a dedicated antenna and the user is
required to provide an antenna. The conformity assessment of the
WA-TX-03-R was performed using Circuit Design’s evaluation board and
antenna (1/4 lambda lead antenna). We recommend that you use our
standard antenna (ANT-LEA-02 or ANT-RIG-02), or an antenna with
equivalent characteristics and performance. For details about our
evaluation boards and antennas, refer to
www.cdt21.com or contact us. If
you use an antenna other than the recommended antenna, further radio
conformity assessment may be required.
2. Supply voltage of the WA-TX-03-R
The WA-TX-03-R should be used within the specified voltage range (4.2
V to 6.0 V).
3. Enclosure
To fulfill the requirements of EMC and safety requirements, the
WA-TX-03-R and the WA-RX-03-R should be mounted on the circuit boards
of the final products and must be enclosed in the cases of the final
products. No surface of the WA-TX-03-R and the WA-RX-03-R should be
exposed.
4. Cordless audio transmitter shutoff
The WA-TX-03-R does not have automatic transmitter shutoff function in
the module. The manufacturer of the final product is required to
design the final product to have such function in accordance with EN
301 357.
EMC requirements according to the R&TTE Directive Article 3.1b
The ESD-test (Electro Static Discharge test) was not performed on the
WA-TX-03-R and the WA-RX-03-R. The WA-TX-03-R and the WA-RX-03-R are
designed for embedding in final products and rely on the enclosures of
the final products to provide the necessary protection. The ESD test
should be performed on the final products incorporating the WA-TX-03-R
and the WA-RX-03-R.
Safety requirements according to the R&TTE Directive Article 3.1a
The WA-TX-03-R and the WA-RX-03-R rely on the final products to
provide the electrical, mechanical, and fire enclosure requirements.
The nominal supply voltage of the WA-TX-03-R is 4.2 – 6.0V and the
WA-RX-03-R is 3.0 V – 5.0 VDC. The worst input currents under normal
operating conditions are 70mA and 45mA respectively. The final product
should be capable of supplying these power requirements.
The WA-TX-03-R and the WA-RX-03-R are entirely SELV (Separated Extra
Low Voltage) when the supply input from the final product is SELV,
i.e. the WA-TX-03-R and the WA-RX-03-R are Class III equipment in
which protection against electric shock relies on a supply from an
SELV circuit and in which hazardous voltage is not generated.
The WA-TX-03-R and the WA-RX-03-R should be installed in the final
products so that the required creepage and clearance distances (within
the final products) are maintained.
Conformity assessment of the final product
The manufacturer of the final product is responsible for the
conformity assessment procedures of the final product in accordance
with the R&TTE Directive.
As to the conformity assessment of the R&TTE Directive Article 3.2
(Efficient use of the radio spectrum), the manufacturer of the final
products incorporating the R&TTE assessed WA-TX-03-R and WA-RX-03-R
will be exempted from its conformity assessment procedures. For
details of how to use the conformity assessment of the WA-TX-03-R and
the WA-RX-03-R, please consult the relevant authorities or accredited
certification bodies.
Notification of the final product
The notification required by R&TTE Directive Article 6 (4) is not
necessary if the final product is used in the harmonized frequency
band and is classified as Class-1 equipment. If the final product is
not used in the harmonized frequency band and is classified as Class-2
equipment, the manufacturer of the final product has a duty to notify
the relevant radio regulatory authorities in the countries where the
final product is sold.
Exemption clause
Circuit Design, Inc does not guarantee the accuracy of the above
mentioned information about the conformity assessment and notification
of the final product. Directives, technical standards, principles of
operation and the like may be interpreted differently by the
authorities in each country. Also the national laws and restrictions
vary with the country. In case of doubt or uncertainty, we recommend
that you check with the authorities or official certification
organizations of the relevant countries.
